Police released this surveillance image to the public during the investigation of Delrio Ivy's death.

"Calls from the public as a result of a recent media report made it possible to identify the actor, David Umstead. The 30-year-old man lives in Pittsburgh but has no permanent address. He will face a homicide charge," said a statement from the Pittsburgh Public Safety Department.
